摘要
随着电动汽车数量持续上升,电动汽车的充电问题亟待解决。传统有线充电方式存在接口磨损、线缆老化、接触不良等安全问题,而无线充电可以很好地避免这些安全隐患。本文参考无线充电相关设计规定,利用ANSYS/Maxwell和MATLAB/Simulink搭建了无线充电基础电路模型,基于PID控制器提出了一种系统恒输出控制策略。通过仿真证明了该系统可实现93.8%的传输效率,并根据输出目标稳定系统输出,提高了系统稳定性。
As the number of electric vehicles continues to rise,the charging problem of electric vehicles needs to be solved urgently.The traditional wired charging method has security problems such as interface wear,cable aging,and poor contact,and wireless charging can well avoid these security risks.This article refers to the relevant design regulations of wireless charging,uses ANSYS/Maxwell and MATLAB/Simulink to build a basic circuit model of wireless charging,and proposes a system constant output control strategy based on PID controller.The simulation proves that the system can achieve a transmission efficiency of 93.8%,stabilizes the system output according to the output target,and improves the system stability.
